No HDMI Output After Flashing Avnet RZBoard Image

ducvietle — Thu, 28 Aug 2025 08:01:52 GMT

Hello,

I’m using the Avnet RZBoard and recently flashed the official image provided by Avnet. However, after flashing, I’m not seeing any output on the HDMI port. The board powers up correctly, and the flashing process completed without errors.

Here are a few more details:

Board: Avnet RZBoard
Image: Official image downloaded from Avnet’s website
HDMI display: Tested and working with other devices
Connection: HDMI cable is properly connected before powering the board

I would appreciate any guidance or troubleshooting steps. Is there any configuration needed post-flashing to enable HDMI output? Or could it be related to image compatibility with specific display types?

Thanks in advance for your help!

Best regards,

Duc Le

How to Interface HC-SR04 Ultrasonic Sensor with MaaxBoard OSM93 (i.MX93)?

Manju123 — Tue, 29 Jul 2025 06:53:44 GMT

Hello community,

I’m trying to interface the HC-SR04 Ultrasonic Distance Sensor with the MaaxBoard OSM93 (based on i.MX93 Cortex-M33). I plan to connect:

TRIG pin of HC-SR04 to one GPIO as output (to send the trigger pulse)
ECHO pin to another GPIO or timer pin (to measure the pulse duration)

However, I’m facing the following issues:

I’m not sure which 40-pin header GPIOs support TPM (Timer Input Capture) functionality.
Is there a TPM Input Capture SDK example for i.MX93 that works with MaaxBoard OSM93?
Where can I get a proper pinmux table for the 40-pin header of MaaxBoard OSM93?

Any guidance, pin mappings, or working code examples would be really appreciated!

Thank you!
